Describe the three stages of cellular respiration and identify the part of the cell in which cach
RUDIKE [14]

Answer: 3 stages- glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+.  A carboxyl group is removed from pyruvate and released as carbon dioxide. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.  The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP.  The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.

Similarities between mitosis and meiosis (as many as possible, I really need help)
vesna_86 [32]
Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. 
so the similarities are: 
-ways for cells to divide 
-same number of chromosome as the original cell 
-both have the basic 5 phases 
-both processes go through chromosome replication 
-Meiosis II is similar to Mitosis 
I hope this is helpful :)))
have a nice day

What does crude oil do to us humans when we burn it and create stuff out of it? is it unhealthy?
Dennis_Churaev [7]

Answer:

Crude oil is used to make the petroleum products we use to fuel airplanes, cars, and trucks; to heat homes; and to make products such as medicines and plastics. Although petroleum products make life easier, finding, producing, and moving crude oil may have negative effects on the environment More than 12 million people live within 1/2 mile of these facilities, and many are exposed to air and water pollution on a daily basis, which can lead to an array of health issues.       Bonus.....People with asthma are at greater risk from breathing in small particles. The particles can make asthma worse. Both long-term and short-term exposure can cause health problems such as reduced lung function and more asthma attacks

This is what i have hope it helps! :)
